Inside Edition investigated crosswalk times around the country to compare how long you would wait when you press the button compared to when you don’t.

At a busy intersection in Miami Beach, it normally takes 63 seconds for the light to change and you have 30 seconds to cross. When pushing the button, Inside Edition found the wait time is the same — 63 seconds exactly.

At an intersection near Temple University in Philadelphia, it took 60 seconds for the light to turn red. Inside Edition then pushed the pedestrian button and once again, it made no difference.

In New York City, there are hundreds of crosswalk buttons and, as far as we could determine, most do absolutely nothing.

Inside Edition’s Chief Investigative Correspondent Lisa Guerrero checked out a pedestrian button she found at Manhattan's busy West Side Highway, near the popular Intrepid Sea, Air & Space Museum.

“It doesn't change how fast I’ll be able to cross the street,” she declared.

So the next time you hit that button, there's a good chance it's a total wasted effort.

Guerrero called the crosswalk signs “false advertising.”

There is a silver lining to these non-functioning crosswalk buttons, however. Research has found that even if the buttons don’t do anything, the “illusion” of control they give actually can actually help people feel calmer.
